l To all whom it may concern Be it known that I, WILLIAM MAYO Van- ABLE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invcntedcertain new and useful Improve ments in Wall-Molds, of which the following is a specification.

The invention relates to molds or forms for use in the; construction of concrete houses, and particularly for use in the con-' str-uction ofthe walls of houses. It has for its primary objects, the provision or 1mproved means for the construction of walls of varying thickness and length from the same parts, whereby the number of diil'erent parts required is reduced to a minimum; the provision of a construction in which the amount of labor in idcnt to assembling and disassembling is re need; the provision of a construction in which the adjustment of the length of the walls can be carried to a high degree of refinement without unduly 1ncreasing the number ofparts of varying dimensions; and the pro-vision of an apparatus which can be cheaply constructed, which can. be operated by unskilled labor without danger of mistakes and which is exceedingly strong and rigid when in position for use. Certain embodiments of the invention are illustrated in the accompanyin drawings, wherein 'igure 1 .is an assembly plan view showing the application of my invention to the construction of walls, Fig. 2 is a section on the li'ne lI -Il of Fig. 1, Figs. 3 was are enlarged detail views of one of the liner bars and the splice plate used in connection therewith, Fig. 3 being a plan view of the parts specified and Fig. 4 being a side elevation thereof, Fig. 5 is an enlarged detail sectional view through one of the spacer bars employed and its guard, Fig. 6 is an enlargement of the right hand end of the section shown in Fig-.2, Fig. 7 isa face view of one side of the portlon of the form shown in section in Fig. 6, and Figs. 8 and 9 are plan and side elevation views respectively of the splice connection between the liner bars at one of the inside corners of the mold.

The elements or units from \which the form or mold is built up consist. of the usual rectangular plates provided at their edges with the butturnedfiauges. These units or Specification of Letters Patent.

WALL-MOLD Patented July 14, 1914.

panels are made preferably in a limited number of standard sizes, and are secured together at the flanges by means of releasable connccting means extending preferably through perforations in the said flanges. In order to secure slight variations in the dimensions of'the walls to be built, such as cannot be secured by the useof the standard plates of varying size, filler plates are employed which overlap the standard panels to a greater or less degree, depending upon the condition to be met, and the two sections of the wall joined by the filler .plate are rigidly secured in fixed relative position'by what may be termed liner bars. These liner bars are secured rigidly to each section of the wall with their-ends adjacent, and these ends are secured together by means of splice members which are secured detacha'bly and adjustably to each of the liner bars. This arrangement provides for the securing togetherbf two adjacent sections of the wall in any desired relation, the connection occurring either between sections of the wall or mold which are in alinement, or between sections which are at an angle. The filler plates employed may be located either .between two sections of wall in alinement, or bctweemtwo sections of wall or mold, at an angle to each other, and may be at an inside corner, or at an outside corner, as will more clearly appear from a fuller consideration of -Fig, .1 of the drawings later. The inner and. outer walls of the mold are held securely in their proper relative position with respect to each other by means of what may be termed space or tie bars, andsuch tie bars, in the preferred form of construction,

also serve as means for securing the liner bars rigidly in position. As will appear more fully later, the liner bars may be placed upon one side only of the mold, ormay be placed upon both sides, depending upon the conditions encountered, and may be placed eitherhorizontally or vertically, or both. Figure 1 of the drawing is .designed to illustrate a variety of arrangements of the liner bars, fillemplates and splice plates, such figure illustrating the ap plication of the elements of my apparatus in :1 variety of locations and conditions.

Referring first to that portion of the mold at the left hand end of Fig. l, and shown in enlarged detail in Figs. 6 and 7, it will be seen that the opposing sides of the mold or form are built up of the panels 11 and 2-2 provided at their edges with angles secured to the plates constituting the bodies of the panels and having outturned flanges. The flanges of adjacent panels abut each other as indicated in Figs. 6 and 7, and are perforated to receive slotted keys 3, whose slotted portions are engaged by the wedge shaped members 4 (Fig.7). Adjacent panels are thus detachably clamped together, and a wall of any desired extent may be secured, depending upon the number of panels employed. A convenient size for the panels is 24 inchesby 24 inches overall dimensions, and in order to provide for varying lengths of walls I have found it desirable to use in connection with such square 24-inch panels other panels 24 inches long but only 12 inches and six inches in width, these three sizes in connection with the adjusting means involving the filler plates and splice members to be hereinafter described, serving to construct walls varying in length by a quarter of an inch.

The two opposing walls or sides of the mold are held rigidly in their proper relative position by means of the space bars 5 whose construction will be very readily undcrstood by reference to Figs. 6 and 7 in connection with Fig. 1. These space bars 5 which are also sometimes known as tiebars, are tapered in order to permit of their more ready withdrawal from the concrete after it has set, and are each provided in their ends with the plurality of slots 6 serving to provide for an adjustment in spacing between the two opposing walls. These space bars egtend from one side of the mold to .the other and pass between. the panels 1 and 2 at their juncture, the opposing flanges of the panels being recessed to permit the passage of the space bars as indicated at 7 in Figs. 2 and 7. Keys 3 like the keys 3 heretofore described extend through the slots 6 at the outer ends of the bars 5 (see Figs. 1, 6, and 7) and through the abutting angles carried by the panels, such keysbeing secured by wedges 4. As indicated in Fig. 6, the bottom bar 5 and the third bar 5 from the bottom are secured at their ends only by keys 3 as just described, but the other two bars 5 (as indicated in Fig. 6) are in addition secured to the liner bars which will now be described.

Extending transversely across the plates 2-2 constituting the inner wall of the form are the liner bars 99, such liner bars being in the form of commercial angles, and being constructed as indicated in the detail views (Figs. 3 and 4). The vertical angles of these bars 99 are provided with the slots 10 for the passage of the ends of the space bars 5, and the ends of the horizontal flanges ..of the angles are provided with the plurality of closely spaced adjusting slots 11 used as hereinafter described, for securing.v

the panels 1 is also lined up by reason of the connection between the linerjba'rsand the outer wall through the space bars. Further in addition to lining u the two walls the liner bars serve as sti eners for such walls. If desired, these liner bars may be used on the outside wall as well as on the inside wall, such arrangement being shown in the upper wall illustrated in F1g.'1wh erein the inner wall is provided w th the liner bars 9 and the outer wall is provided with the liner bars 9 the space bars 5 in such case passing through the vertical flanges of both the liner bars 9 and 9".

The liner bars also perform another function, which is-to provide a connection between adjacent sections of the wall where a filler plate is interposed between 'such sections of the wall, in order to securean'y desired adjustment as to the length of the wall. Where connection between adjacent,-

wall sections occurs at the corner the splice plate is preferably triangular as indicated in the plate 13 shown in Fig. 1 and In detail in Figs. 8 and 9. The two adjacent wall sections at this point are joined by means of the. lap filler plate 14, so that the relation between the Walls may be adjustedto any desired degree of fineness by varying the lap between the filler plate 14 and the adjacent Walls. secured to the adjacent panels but is held. in position by the concrete. Before the. con-- rrete is applied the plate may be temporarily held against'movement by any desired temporary holding means such as braces to the opposite wall or may be held by the workman until sufficient concrete is supplied behind the plate to prevent its ac cidental movement. The spacing of the adjusting slots 11 (Fig. 3) at the ends ofthe liner bars is made slightly greater than the spacing of the slots 14 in the splice plate 13, so that a vernier adjustment may be secured between the liner bars and splice plates. For instance if the spacing of the slots 11 is made one inch and thespacin or the slots 14/ is made three quarters 0 an The filler plate 14 'isnot inch, the splice plate when placed on the niosgmor bers on each other a quarter of an inch, so

thata very fine adjustment may be secured without an unduly closespacing of the slots. in .the two members; As indicated in Figs. 8 and 9, the splice. late 13 is secured to the liner bars 9 audit, y-means of slotted keys 3 held by wedges' i corresponding in all respects to the members 3 and 4 heretofore tie scribed. In order that the endsof the panels adjacent the splice plate 13 may be held. against movement, the relatively short slotted tie bars 15 (Fig. '8) are keyed to the angles of the panels by means of the keys 3 and wedges a, and extend through the end slots 10 in the liner bars '9 and 9, and are held by wedges 4: similar to those heretofore described as holding the ends of the space bars to the liner bars. The tie bars 15 may be used in anycase where it is desirable or necessary to dispensewith the space bars 5, the liner bars being in that case held in position to the one wall by the short tie bars. It will be seen therefore that the two wall sections approaching at the corner may be rigidly and adjustably secured together by means of the splice plate attached to the liner bars, and that any desired adjustment is possible by reason of the filler plates is which oierlaptthe two wall sections to a greater or less degree.

In some cases it may be desirable toem ploy filler plates in the straight portion of the mold instead. of at the corner as heretofore described, and in such case the system..

of joinder remains substantially the same. The numeral 16 as applied to the left hand wall in Figs. 1 and 2 indicates filler plates supplied in the straight portion of the wall. In that case the liner bars 9 and 9 are in alinement, and a rectangular splice 17 is employed for securing the liner bars 9 and 9 "t0gether, such plate overlapping the ends of the two liner bars. This splice plate 17 .is provided with the series of perforations I corresponding to -the perforations in the splice plate 13, so that a Vernier adjustment between the two liner bars is secured, and the filler plates 16 may be made to overlap the wall sections a distance sufficient to se- In this construction the adjacent ends of the panels 2-2 are provided with the short tie bars m1515' similar to those of Figs. 8 and 9,

such bars being keyed to the flanges ofthe panels 22 and extending through the end slots 10+10 in the liner bars '9 and 9 (F ig. I the wall is provided with liner bars 9 (Figs. 1 and 6) through which the space bars 55 extend and to which such bars are securedby the wedges 4- 1. The adjacent ends of the panels 1-l onoppositesides of the outer filler plate are secured'to the bar 9* bymeans of the short tie bars 15-15 (Fig. 1) as heretofore described for holding the edges of the plates 2 2 to the bars 9 and 9 In the upper righthand corner of Fig; l is illustrated the application of the splice plate to the connection of exterior liner'bars, such splice plate" being indicated by the reference-numeral 18 and serving-to con-' nect the liner bars 9 and 9 the' connection. between the splice plate and theliner bars being substantiallythe same as heretofore described with respect to the splice plate 13.- An outside corner filler plate 19 is employed in this case to fill the gap between the two walls approaching each other at aniangle. Fig. 1 illustrates the application of the connecting means heretofore described, in a number of diilerent conditions, whose apthe drawing, withoutfurther description.

I I In order to prevent the concrete from filling the slots 6 in' the space bars (Fig. 6-) when such slots lie between the side walls, and so prevent the ready withdrawal oit'the barsafter the concrete has set, the U-shaped guard member 20 indicated in Figs. 5 and 6 preferably employed. This guard member 20 extends substantially from one side {wall to the other and incloses the space bar 5 in such manner as to prevent the access of the concrete to the/perforations through the bar, so that after the concrete has set the bar is free to slide through the guard, such guard being left permanently embedded in the concrete.

Having thus described my invention. and

illustrated its use, what I claim as new and desire to secure by Letters Patent is the following.
